Easter egg: When you insert any of the 6 movie DVDs in the Star Wars saga, once the FBI screen pops up (red in Episodes I, II, IV, V, VI; and blue in Episode III), enter a number between 1 and 3 (and press Enter if needed). Once the Star Wars logo and the Episode number disappears, a menu with the planet that you chose (and not what the DVD randomly chooses) will load.
Easter egg: On the DVD, if you use the Infinite Improbability Drive, you have a chance to see the cartoon that Deep Thought watches. There is no way to access it via menus.
Easter egg: Under Join the Brotherhood (Magneto's side) Go to Features. Then Deleted Scenes. Press "More" until you find the scene called "Henry Warns About Magneto". Highlight it, then press the left arrow to highlight an "X". Press enter and you will get to watch a short 2005 promo for the movie. Under Take a Stand (X-men side), this feature requires you to highlight "X-men land the chopter" then press the left arrow to highlight a "Magneto Symbol".

Also, on the Special Features' second page, hit left on your remote and the sign with "Zoinks" under it will light up, then hit Enter.
Easter egg: There's a short documentary on the DVD about the subliminal message cartoon that triggers River. To get to it, put the cursor on play on the main screen.

Easter egg: 3 easter eggs on German edition (G-41088-ST-FSK): one concept shot of objects, two fully rendered but dumped scenes. Elements of these scenes have been used in the final movie, but at another time and place. 1) go up in the main menu to highlight 2) go up in special features -> activities (Extras > Spiel mit!) 3) go left in the language selection.
Easter egg: 2nd disc: Go into the Great Hall and choose "The Quest of Sir Cadogan". During the introduction to the challenge, between the part when you see Sir Cadogan sleeping (maybe) and when he gives flowers to a girl, hit the left arrow on your remote and you'll automatically go to the picture gallery (which you will also get to if you play the challenge and get the highest rank). You'll still have to play the challenge afterwards, though, unless if you hit Menu.
Easter egg: On the bonus disc, under 'Deleted Scenes', highlight 'I Like Riddles'. Click left three times, a black dot will appear, select it and you can view the names of the winners of the Ultimate Pirates of the Caribbean Fan Event.
Easter egg: On the main DVD menu screen, when play is highlighted, press up. You will highlight one of the crystals. Press enter, and it will take you to a screen with a bunch of different character's faces. Press enter on any of them, it will give you a soundbite from that character. Also, you can highlight the two crystals on the bottom of that page that are on either side of the main menu option that will give you two other soundbites. On the main menu screen, you can't seem to highlight the other crystal. I don't know why.
Easter egg: At the main menu, go to Extras and press Enter. With the words "Santa Claus The Making Of The Movie", press left once and the toy reindeer will turn red. Press enter and a behind the scene clip of the reindeer running will play. This easter egg can also be accessed by going to Extras, going to Main Menu and then pressing right once.
Easter egg: HIDDEN BONUS MATERIAL on the Special Extended DVD Version: There are two secrets on the discs containing the film, one on each disc. Instructions for both: go to the Scene Index on either disc, then scroll down to the LAST scene (either "The Council of Elrond" on Disc 1 or "Official Fan Club Credits" on Disc 2), then scroll down one more time. On the first DVD, a little ring will appear next to the line "new scene." Click Enter. This leads to an introduction by Peter Jackson and the MTV Movie Awards parody on the Council of Elrond (starring Jack Black and Sarah Michelle Gellar), which isn't suitable for children (and does not appear in the UK version because of the BBFC). On the second DVD, scene 48, click on the number 48 - on the right side of the screen - and the silhouettes of Barad Dur and Orthanc appear just underneath, click it. You'll see another introduction by Peter Jackson, and the Two Towers cinematic preview trailer: the one played in theatres after the Fellowship of the Ring, towards the end of its running period.

The unlocked features include a stunt rehearsal reel and CG demo.
